We Are No Dinosaurs: H Bombs Potentially Save Lives, Whereas PC kills

March 18, 2018

I long advocated comet and asteroid defense. The subject is intricate, with high stakes, even more interesting as the very strange reactions it brought.

Years ago, I claimed that H bombs were the ultimate, and necessary tool to achieve security. At the time, “experts” were ruling out nukes. Contemporaneously, I had a major fight with a (decorated) geophysicist about my claim that the Earth functions as a nuclear reactor, thus driving the Earth magnetic field, which protects the upper atmosphere from stripping by the solar wind during Coronal Mass Ejections (which is, we now know the way Mars’ atmosphere was stripped). In my opinion both experts’ opinions were the fruit, not of science, but of the Political Correctness which fed them (they got to their expert position not thanks to their smarts, but thanks to being PC).

Political Correctness, in this case “nukes are evil” was so great at the time that “experts”, to achieve astronomical moral superiority over the moral turpitude of the ilk of yours truly, the moral turpitude of those who tell the truth, pontificated idiotically that H-bombs would be inefficient, unsuitable, inappropriate, and that, to promote their usage, was, besides criminal, the mark of a lack of scientific culture. Moreover, they added, impacts were impossible in the foreseeable future.

Here is an update: the old “experts” were wrong, like 100% wrong, peer-review journal and the US government recognize, it is my pleasure to reveal.

Siding Springs comet, the smallest one is even more dangerous, because of its speed. Europe landed, and orbited with Rosetta the bigger one… which is a tenth of the largest comet known. As comets fly by, they can destabilize others, or asteroids.


A new generation of expert has arisen, who say exactly what I used to say, the obvious. The latest study, in a Russian lab, mimicked nuclear blasts, using lasers (whose energy, just as a nuclear bomb is mostly photons, initially). A US study, on project Hypervelocity Asteroid Mitigation Mission for Emergency Response (HAMMER), concluded the same. New facts have come to the surface.


The probability of impacts, as I said in the past, was underestimated:

As demonstrated in the Tunguska impact in Siberia, “impacts” of a less than 200 meters across bolide has a high probability to end as an airburst. Tunguska flattened 2,150 square kilometers of forest, destroying 80 million trees. That’s a circle with a diameter of 50 kilometers. In other words, exploding above some of the largest city on Earth, it could kill up to 30 million people, annihilating Tokyo-Yokohama, Mexico City, New York, Moscow, the greater Paris, etc… Initially it was thought the explosion was up to 30 megatons TNT, but then it was realized one should take into account the momentum of the disintegrating bolide, just as in the case of a hollow charge to penetrate armor. That lowered the yield to no more than 5 megatons!

A stony asteroid of about 10 m (33 ft) in diameter can produce an explosion of around 20 kilotons, similar to that of the Fat Man plutonium implosion bomb dropped on Nagasaki, Data released by the US Air Force’s Defense Support Program indicate that such explosions occur high in the upper atmosphere more than once a year.

The 1930 Curuçá River event in Brazil, observed by many, was an explosion of a superbolide that left no clear evidence of an impact crater. A smaller air burst occurred over a populated area in Russia on 15 February 2013, at Chelyabinsk in the Ural district of Russia. The exploding meteoroid was an asteroid that measured about 17 to 20 metres across, with an estimated initial mass of 11,000 tonnes, and inflicted over 1,200 injuries (mostly from flying glass, like a nuclear blast)… It would have been worse, had it streaked closer to the city.


ATLAS, the Asteroid Terrestrial-impact Last Alert System:

So now the good news, thanks to our old friends at NASA, ATLAS is running, with one telescope on top of Maui at 3,000 meters, and the other on top of Mauna Loa, 100 miles away, at 4,200 meters.    

ATLAS is an asteroid impact early warning system developed by the University of Hawaii and funded by NASA. It consists of two telescopes, 100 miles apart, which automatically scan the whole sky several times every night looking for moving objects. On the side it has already detected several comets, and 1,200 Supernova, mostly type 1a, among other scientific prowesses. It has also discovered 17 Potentially Hazardous Asteroids…

Second good news, a new generation of experts, American and now Russian, has established that nuclear bombs would be safe and effective to dispose of a dangerous impactor detected too late to nudge it away… Besides, they would be the only way (as I used to say).   


Blowing off skeptics with the Hypervelocity Siding Springs Comet:

Some fanatics, outwardly humanistic, inwardly the opposite, will sneer that my desire to find some use to thermonuclear fusion is pathetic: who cares if a given city has non negligible probability to be vaporized by heavens in the next 100,000 years?

However, the probability is much higher than Conventional Wisdom has it. And a new reasoning will be deployed below, not found in the scientific literature, to my knowledge.

An example was the Siding Spring comet. Nobody expected this sort of comet. It zoomed on what looked like a straight line through the Solar System, passing Mars at 56 kilometers per second. A typical speed for a meteorite (and probably Tungunska) is 11 kilometers per second.

As really great, although female, physicist Émilie Du Châtelet demonstrated in the Eighteenth Century, the energy of body of mass m going at speed v is ½ mvv. So energy per unit of mass augments as the square of the speed. Thus one kilogram of the Siding Spring Comet had 25 times the energy of one kilogram of Tunguska bolide. Add to this the fact Siding Spring was much smaller than its big tail advertised: only 400 to 700 meters across. Siding Spring passed very close to Mars (140,000 kilometers, half the Earth-Moon distance). If Siding Springs had hit Earth, that would have been probably at an angle, and it would have liberated an amazing amount of energy

Computer simulation show that a 200 meters diameter comet going at 11km/s would explode with an energy of 30 megatons. If the comet were 650 meters: 30 x 40 megatons, say: 1,000 megatons (Siding Springs diameter: 400-700 meters). Multiply by 25, from the v^2 factor of Émilie Du Châtelet: 25,000 megatons of TNT. The average penetration angle would be 45 degrees, giving an average trajectory of hundreds of kilometers by hypersonic surfing of the shock wave on the upper atmosphere, say 600 kilometers over 10 seconds. Acceleration: 56,000 meters/sec/10 seconds, in other words 5,600 gs, more than 5,000 the acceleration of earth’s gravity.

These are orders of magnitude. Maybe the comet would surf the atmosphere over a minute, etc. In any case, no solid body, a fortiori a fragile comet, can withstand thousands of gs. It will disintegrate. As it does, it would fry everything in its path. If it surfs two minutes, it could leave a trail of devastation hundreds of kilometers wide, over thousands of kilometers. And guess what? No impact!


Some mysterious degradations of living conditions in recorded history are so far unexplained. Volcanoes, of course are generally the prime culprit, as I long suspected, and explained, with dinosaurs:

Chinese and Romans records indicate a spectacular deterioration of conditions in the Sixth Century. Volcano, or impact? It seems two distinct eruptions were culpritRecently, mainly from the work of some researchers in France, mass deaths in Europe from starvation in 1257 CE, were explained by the explosion of a giant volcano on the island of Lombok, bringing down the kingdom there. The explosion of Thera/Santorin brought down Cretan civilization, thanks to tsunamis, ash, quakes, etc…  

If an impact was found to have occurred in recorded history, with catastrophic consequences, instead of still another crazy volcano, the probability of those extraterrestrial events would be jacked up. In the scenario I gave, the impact from a fast-moving, small comet, there would be no traces on the ground.

In any case, the pollution of questions of life and death by Political Correctness can be utterly grotesque: it was clear all along that, in some configurations, we would have to nuke asteroids or comets. To pretend otherwise was idiotic, corrupt.

Having to use nuclear energy to save ourselves is very good. And ultimately, we need controlled, sustained thermonuclear fusion. If we had it now, the CO2 catastrophe (and many other catastrophes) would be avoided. Nuclear is our friend, if, and only if, well done.

What’s never our friend is any notion that it is philosophically correct to believe that fancy and corrupt notions of so-called Political Correctness trump the truth. It’s not just that nothing trumps reality. By faking reality, we reject altruism.

Pluto’s Cosmic Impact

February 27, 2013

Abstract: There is a real, serious impact threat, from small asteroids, and, much worse, long period comets. Yet our great leaders are not too interested, because they prefer the world population as they will it to be: ignorant, despondent and impotent. Cutting science budgets in the guise of austerity helps. So they are busy cutting: austerity for humanity, and anything that makes the honor of mankind, wealth for those who lead us towards oblivion.

A world unwilling of solving problems to the point of being incapable to do so, is perfect for those who profit from the established order, and yearn for divinizing celebrities and more exploitative stagnation rather than real progress and empowerment of the commons.

Far Away Meteor’s Fireball: 27 Kilometers High (90,000 ft)

The comet problem is a case in point. It’s perfectly solvable. But it is left unsolved as a paradigm that unemployment is better than all and any alternative, including cosmic catastrophes. The ways of Pluto are subtle, and vicious.

Don’t ask for whom austerity tolls, it tolls for thee, and any science, wisdom or knowledge you may want to acquire. Admire the celebrities: they are the best lives you will ever get.

In less than four years, two nuclear explosion sized asteroid impacts were observed over continental plates. One was more than four times the power of the Hiroshima bomb (Sulawesi in Indonesia, 2009), the other was 33 times Hiroshima (Urals, 2013). So much for the notion that these things are rare and innocuous events. Just above land, I know of four explosions of city killers in 105 years.

(There have been eyewitnesses of major explosions at sea, too; a scientific debate is ongoing about whether there was a truly giant, country killer impact south of New Zealand, 5 centuries ago.)

Only 1,500 people were hospitalized by the shock waves of the Ural meteor, because as luck had it, the meteor was on a grazing trajectory when it collided with the atmospheric wall. It streaked through the wall sideways for 32.5 seconds before experiencing three explosions. The first one, and strongest, happened 27 kilometers above the Urals, 60 kilometers south of the center of a city habitated by one million people.

If the asteroid had been a minute late, on the same trajectory, Tokyo may have been hit. If the meteor had been 30 seconds ahead, on the same trajectory Moscow, moving at 30 kilometers per second, would have caught up with the meteor. In either case, the damage on the ground would have been considerable, and massively lethal.

Why? Because the angles of entry would have been much sharper in either case than they were above the Urals. So the asteroid would have delivered its 500 kilotons, 33 times Hiroshima, much lower. Low enough for either capital to have been partly disintegrated.

For those who want to have a good laugh, zombie style, let them be appraised of the following fascinating twist. The deliriously clever Soviets had installed an automatic nuclear retaliation system (“Dead Hand”) in case Moscow had been destroyed by surprise by the vile capitalists. (Western Strategic Submarines could have hit Moscow in three minutes, hence the hair trigger paranoia.)

“Dead Hand”, also known as “Perimeter” , worked by detecting flashes and seismic waves, and then firing nuclear tipped rockets automatically. The Russians have been coy about whether the system is still in use. May be that is why Putin was so ashen faced when speaking about the Ural meteor. Putin may have been told of my little computation above: 30 seconds or so later, and the meteor may have released 500 kilotons above the Kremlin.

When the folly of men insults the might of heavens, fireworks are guaranteed…

The debate about space impactors has been deflected towards the wrong problem, the obviously silly red herring, the problem one should not worry about, the non dangerous problem. That’s indeed the case when an asteroid CAN be deflected.

Deflection, per se, means one has decades to do it. Thus it is not an emergency, by definition. Why to assume celestial mechanics and happenstance will be that accommodating? Is the Solar System a restaurant where one makes reservations when one feels like it? Of course not. Thus asteroid deflection is the wrong problem. Asteroid deflection is a bit like worrying about being eaten by a shark while skiing out of bounds. What needs to be addressed is a different problem, impactor interception & destruction.

Why so much talk about deflection, when annihilation of the offender should be the focus? Why so much denial? Why change the conversation from a clear and present danger, to talk about a red herring?

The real danger is long period comets: they are huge, unpredictable, undetected, and the warning would come only with months to spare.

So why don’t we talk about them?

Is this blatant denial related to other difficulties we are experiencing, such as the Greater Depression, the Asphyxiation of the Biosphere with man-made greenhouse gases, the Waning of democracy, the Blossoming of Plutocracy? Yes to all.

The refusal to solve the space impactor problem is a baby example of the mood that enables the rule of plutocracy rather than the rule of reason for all.

One avoids to talk about the cosmic difficulty at hand to avoid a mood that plutocracy finds politically dangerous: solving problems and one can, you know, before we know it, solve the problem of rogue finance, corrupting fossil fuel industry, etc …. As NASA put it in 2012:
“For non-technical reasons, nuclear explosions would likely be a last resort, but IT IS ALSO THE MOST POWERFUL TECHNIQUE…
The nuclear option would be usable for objects up to a few kilometers in diameter.”

Nobody Can Resist Me

Nobody Can Resist Me

So what are we waiting for? Well we are waiting for plutocracy to keep on impacting our world ever more deeply. That’s what the plutocrats want. They want to deeply impact civilization with the sheer glory of their rule.

As I write this the threats of austerity cuts are already affecting the science budgets in the USA by more than 5% (from the looming “sequester”, which has already forced scientific agencies to implement thousands of cuts). In the European Union, scientific cuts are turning into a massacre.

Indeed, in the European Union, the cuts to the scientific budgets are in excess of an unbelievable 13%. Another victory for Kanzler Merkel and the very wealthy heir, David Cameron! Instead of cutting science, why don’t the politicians put a 93% tax on multi-millionaires, to finance science and education?

Putting a 93% tax on the wealthiest is what Republican president Eisenhower did to reimburse the World war Two debt. So why not? Why to throw the baby, but not the dirty bath? Answer: because the politicians would lose the friends that will make them so incredibly rich tomorrow. Politics would not be a lucrative career anymore.

This is a point Beppe Grillo is making in Italy, and now he has 18% of the Italian Parliament to show for it.
OK, Eisenhower taxed the wealthy when Lincoln’s party was really republican, instead of being thoroughly plutocratic, as it is now. In Eisenhower’s time, millions of citizens of the USA could go to the most advanced schools, for free. Including Medical School. Somebody will a normal job could feed a family and provides it with a roof without excessive debt (now a couple can barely do that with 2 jobs and excessive debt, as long as oil is not too expensive).

The mood the careerists such as Cameron, Merkel and the so called Republicans in the USA, want to avoid absolutely, is the mood of solving the problems at hand, with the technology at hand.

Indeed such a mood could impact hard plutocracy itself. Plutocracy is an even mightier threat for civilization than any comet. Any comet could be dispatched with a 200 Megatons thermonuclear bomb, should be act swiftly. In other words, disposing of a comet would be a technological project much easier to implement than getting rid of plutocracy. Why? Common people would understand that something four kilometers across at 40 kilometers per second would affect them adversely.

Yet, common people have been hypnotized into believing that plutocracy is their best friend. It’s their new religion. They salivate when beautiful people show up on the screen. they live through them. They don’t feel like the lobsters they are, slowly cooked for dinner.

Solving problems is a very bad habit for a society to have, when it wants plutocracy to rule. Because plutocracy itself is a problem. The worst chronic problem. So one may fear that plutocracy itself would be solved, by problem solvers… As it was under the Roman republic, for five centuries.

Roman emperors, the “Princeps”, those “First men in Rome” who stole power from the republic, were fully aware of this. So they avoided solving problems scrupulously. One could make a curve of problems solved by the Roman state, and see that it goes down to basically zero once the fascist empire started to rule in full.

A society that makes a habit of solving problems will solve excessive plutocracy first. because only the intelligence of the People is freed from celebrity cult, and starts to contemplate the universe at large. That is why one observes that highly innovative societies were also highly revolutionary socially, and cut down to size their own plutocracy. First.

For example the golden age of Greece was preceded by massive, well, drastic, revolutions, starting with the draconian Draco himself in Athens (around 622 BCE) Sparta would later free Athens from tyranny). And of course Solon in Athens, probably inspired by Draco.

During the French revolution, in 1792, as plutocratic armies invaded the country from all direction, the Polytechnique and other engineering schools were founded. The idea was to defend the homeland of human rights supreme with smarts. Immediately new explosives were invented at Polytechnique, and put to good use at Valmy, a few miles from Paris, to stop the Prussian Duke of Brunswick, who had promised to do to the Parisians what Hitler would do to the Jews, nearly two centuries later (tradition, tradition…)

Thus the Beatles were wrong when they sang hypocritically against revolution… (While racking the cash, and rubbing against the plutocratic order; Mc Carney married the Kodak heiress…) The revolutionary spirit infects all dimensions, once it’s allowed to grow in one of them.

During World War Two, the USA functioned pretty much as an equalitarian republic. Old French revolutionaries, ancient republican Romans, 22 centuries ago, Athenians 25 centuries ago, would have recognized the spirit immediately: out of the many, one, liberty, equality, fraternity… And plenty of ideas. The US navy in the Pacific, or the scientists involved in the atomic bomb project were pretty much self governing bodies, guided by truth.

Solving problems leads to an obsession with truth. Thus, if one wants to avoid the truth, one better stick to avoiding problems, and the solutions they bring. Thus the Roman emperors discouraged paradigm changing technology. As the mood of changing what could be changed could prove contagious, and thus threaten the order they ruled over, they astutely felt.

In the case of the threat of a space impactor, the solution is obvious. It calls for maximal, but existing, technology. The interception of the offensive object with a thermonuclear bomb is only rocket science, not Quantum science. It’s nothing off the shelf.

But to decide to do what can be done, and could do it efficiently, would recognize the preponderance of the metaprinciple that establishing an order of more or less vital priorities and taking care of high ranking priorities ought to rule over economic considerations.

It is this (meta)psychological subtlety that holds back Spaceguard.

After the Ural meteor’s strike, the Russian Prime Minister called for constructing Spaceguard. This would be intolerable to the world financiers and profiteers: if one used economic power for something useful, would not the world of finance supreme look irrelevant? Where would the spirit of enterprise stop? With finance’s heads on spikes?

Better to stick to the usefully childish, such as the muscle bound Princess of the USA (see the note about the meaning of the word “Princess”) giving a “best movie” award to still another motion picture glorifying wars of the USA in the Middle of Eurasia.

Such movies are much useful, to the plutocratic order. Hollywood seems to have a factory churning them out, and the Main Stream Media (“60 Minutes”, say) re-iterate the message.

Such movies, with their partial view of history, insure that We The People of the USA learn what a continual pain the Middle Easterners have been directing towards the USA, ever since they have oil, and have to be continually encourage to fork it all over to Wall Street.

Iran is particularly insensitive that way, as the USA worked hard changing the government there after the Iranian People voted for the wrong guy (Mossadegh) in the early 1950s. Then the USA installed by a real Shahanshah (“King of Kings”) with the help of its friend of the CIA, Khomeini. It’s good to be reminded of all this, and celebrate the “greatest country on Earth” (Shall we give it the title of Country of Countries?).

So never mind comets, asteroids, H bombs and heady stuff. Celebrities is where it’s at. Muscle and glitter. Now Sandberg, the Facebook woman, before that the Google woman, and before that, for more than a decade, the Larry Summers/Financial derivatives woman, since he got to meet her as an undergraduate when he was president of plutocratic Harvard, is coming out with a book to teach women how to succeed. I guess, that’s done the old fashion way, by meeting the right guys and accumulating that way a “stellar resume“.

They sleep, thus they rule, and they are even sleeping at the wheel.

Those who rule know how to take care of what’s important in the universe: the awe that become them. Let the universe take heed.

Note: Ms Obama is given the title of ‘First Lady’. Yet, as anybody who knows Latin will testify, this is exactly what “Princess” means! It’s wonderful to discover that aristocracy is as American as motherhood.
